Meanings

  1. 1 concealed hand (mahjong: hand with no called tiles from others)
  2. 2 (coll.) to know something inside out

Tips

usage
In mahjong, 门清 scores extra because no tiles were drawn from other players' discards. In Beijing slang it gets erhua-ized to meaning completely clued in.
culture
Compare Japanese riichi mahjong's menzen () — same root concept, concealed hand bonus.
